The glymphatic system, which was identified in 2012, is the network that clears out waste products from the brain and central nervous system. Essentially, this system is the way that fluid surrounding the brain and spinal column moves out of the brain, carrying waste products with it. The glymphatic system is found in the areas … Read More
A recent study shows that low-dose lithium may act as a senolytic.[ref] This has important implications in healthy aging – including preventing mortality from respiratory diseases, such as COVID, and neurodegenerative diseases like Alzheimer’s. First, let me go into a little background information on lithium and then cellular senescence. Next, I’ll explain the new study … Read More
New research on COVID-19 shows the important role of cellular senescence in the high mortality rates in the elderly. Elderly people are much more vulnerable to the flu, respiratory infections, and sepsis than middle-aged or younger adults. We all know that when grandma gets the flu in the nursing home, it is a serious matter. … Read More
A pre-print study posted in May 2021 shows positive results in a clinical trial with the goal of reversing early Alzheimer’s disease. This is big! An attitude of acceptance that Alzheimer’s is a non-reversible fate prevails in medical practices, and a positive clinical trial showing marked improvement in many participants is wonderful to see. The … Read More
Kind of like pornography, we all know aging when we see it. There is a specific point when suddenly someone looks old. Like they have crossed some invisible threshold, moving from healthy and older into the twilight area at the end of life. I’m not talking about gray hair or laugh lines that became more … Read More
Alpha-ketoglutarate is a key molecule produced in your cells. Recently, research studies have shown that it may play a key role in healthy aging, including increasing healthspan and lifespan. What is alpha-ketoglutarate? Alpha-ketoglutarate (αKG) is a molecule that cells produce. It has several important functions in the body:[ref] It is involved in the Krebs cycle … Read More
A recent study on sleep and dementia points out (once again) that sleep is essential for good health in aging. The study found that decreased sleep, such as 6 hours or less per night, during your 50s and 60s increases the risk of dementia in your later decades by 30%. Quality sleep is foundational for … Read More
Mitochondrial dysfunction and elevated oxidative stress are part of the root cause of aging. With poor mitochondrial function, cells can’t perform at an optimal level, leading to an increase in ROS (reactive oxygen species). Oxidative stress, due to an increase in ROS, increases the risk of cognitive decline, inflammation, heart disease, and insulin resistance. So … Read More
I read a lot of studies on health and genetics, and I keep finding research on the mineral lithium popping up. Topics such as circadian rhythm dysfunction, Alzheimer’s disease, telomere length, type 2 diabetes, and obesity…all linking to lithium? The rest of this article explains the research showing the importance of this mineral in our … Read More
TNF-alpha (tumor necrosis factor alpha) is a proinflammatory cytokine upregulated in aging. TNF-alpha acts as a signaling molecule in our immune system and is important in our innate immune response. But chronically elevated TNF-alpha is one cause of the diseases of aging. Inhibiting chronic inflammation is one tool available for longevity and healthspan. This article … Read More
